Subject: High Speed Amplifiers Topic: Making High Speed Amp
... Building a high speed amplifier circuit, with bandwidths in the mega-Hertz (MHz) range, requires an understanding of the amplifier specifications in great detail. As the bandwidths of the amplifier increase, the amplifiers specifications become even more necessary to understand due to the fact that ...

Due to this fact, the proposed idea is suitable for low voltage applications too, because it needs just fewer voltage (about 3 over drive voltage) to start its performance. Hence, the proposed CMFB circuit has high accuracy and high speed besides it can employ the low power c ...

DN308 - 100MHz Op Amp Features Low Noise Rail-to-Rail Performance While Consuming Only 2.5mA
... source is not grounded but rather looks into R3 and the high impedance op amp input. This fact combined with the low input voltage noise makes the circuit well suited to both large and small photodetectors. Using a small photodiode with 2.5pF junction capacitance and adjusting parasitic feedback cap ...

Negative feedback
Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.Whereas positive feedback tends to lead to instability via exponential growth, oscillation or chaotic behavior, negative feedback generally promotes stability. Negative feedback tends to promote a settling to equilibrium, and reduces the effects of perturbations. Negative feedback loops in which just the right amount of correction is applied with optimum timing can be very stable, accurate, and responsive.Negative feedback is widely used in mechanical and electronic engineering, but it also occurs naturally within living organisms, and can be seen in many other fields from chemistry and economics to physical systems such as the climate. General negative feedback systems are studied in control systems engineering.
